Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If radar signals are transmitted in the GHz to THz frequency range for object detection, then object detection capability is improved, but interference with 5G NR wireless communication networks occurs due to overlapping frequency ranges
Solution Approach 1:
The patent implements dynamic adaptation of communication parameters based on radar signal measurements. The system continuously monitors the environment using radar signals and adjusts communication parameters (transmit power, beamforming configurations, frequency selection) in real-time to avoid objects and minimize interference, transforming the static communication system into a dynamic one that adapts to changing environmental conditions
Solution Approach 2:
The system employs feedback mechanisms where radar signal receive properties (such as reflected signal strength, time of flight, Doppler shift) are measured and used to adjust communication parameters. The communication system receives feedback about the local environment from radar measurements and modifies its operation accordingly, creating a closed-loop control system that optimizes both detection and communication performance
2Reliability
If transmit power is increased to maintain effective wireless data communication, then communication reliability is improved, but power density increases causing interference with objects in proximity
Solution Approach 1:
The patent applies local quality by adjusting communication parameters specifically for different spatial regions and directions. Using beamforming configurations, the system directs communication energy toward specific spatial zones while avoiding regions where objects are detected by radar measurements. This allows high transmit power to be focused only where needed for reliable communication without unnecessarily increasing power density in directions where objects are present
Solution Approach 2:
The system dynamically changes communication parameters including transmit power level, beamforming weights, frequency selection, and modulation schemes based on radar-derived environmental information. When objects are detected in certain directions or when channel conditions deteriorate, the system adapts parameters to maintain communication reliability while minimizing harmful effects on objects through precise spatial and spectral management
